Patent GB-777517-A (GB)
Title: Manufacture of nicotinamide
Inventor: GASSON EDWARD JAMES
Filed: 1955-04-20
Abstract: Nicotinamide is prepared by hydrolysing 3-cyanopyridine at elevated temperatures in an aqueous medium containing as a catalyst a compound having a solubility in water of not more than 0.1 per cent at 20 DEG C. and whose saturated aqueous solution at the same temperature has a pH value between 8 and 11, terminating the reaction when not more than 80 per cent of the 3-cyanopyridine is converted into nicotinamide and recovering nicotinamide and unreacted 3-cyanopyridine from the reaction mixture.  The hydrolysis is preferably conducted at a temperature within the range 100 DEG  to 130 DEG  C.  Specified hydrolysis catalysts are magnesium oxide, calcium carbonate and barium carbonate.  The nicotinamide may be recovered by distillation and extraction of the residue with acetone. The distillate containing the unreacted 3-cyanopyridine may be passed through an ion-exchange resin to remove ammonia and the resulting solution recycled to the hydrolysis process.  The nicotinamide may also be recovered by direct extraction of the aqueous reaction mixture with benzene, toluene, carbon tetrachloride, petroleum ether or chloroform.  In the Provisional Specification, magnesium carbonate is also specified as a hydrolysis catalyst.  Specification 563,184, [Group IV], is referred to.

In a cartridge-operated fastener-driving tool a washer-carrier 7 is slidably mounted on the forward end of the barrel 1 and is adapted to be thrust forward against the structure receiving the fastener by the exhaust gases escaping through vents 2 in the forward portion of the barrel. In one form the carrier 7, Fig. 1, is rigid with a sleeve 8 urged forwardly by a spring 9 located between a shatter guard sleeve 5 and a tube 4 rigid with the barrel carrying block 3. A flange 1a on the end of the barrel limits the forward movement of the carrier 7. The exhaust gases from the vents 2 enter the annular space between the barrel 1 and tube 4 and exert pressure on the carrier 7. In another form the washer carrier 16 is formed with a radial recess for a retaining ball 17 which partially extends into an annular groove 19 in the barrel 11, which groove permits relative axial displacement between the barrel and carrier. The vents 12 lead to an annular space between the barrel 11 and splinter guard sleeve 14 so that the gases can press the carrier 16 forwardly.

Title: Improved delay action device for fuzes
IPC: F42C14/06
Filed: 1940-07-13
Abstract: 572,571. Projectile 'fuzes. TEMPLE, G., and CARR, J. D. BAKER-. July 13, 1940, No. 11685. [Class 9 (i)] Delay-action devices in bombs and projectiles are regulated by the " creep " action of rubber ; such action may also be used to effect the selfdestruction of the missile if firing fails to occur on impact. In the bomb fuze shown in Fig. 1, the firing-pin a is coupled by balls d to a spindle c, a reduced portion c<1> of which passes through a rubber ring h. A rotatable sleeve e, having holes for the release of the balls d, is connected by a stud e<1> to one end of a torsion spring e<2>. The stud is normally locked by a frangible plate e<4>. When the bomb is dropped, the spindle c and striker a are retracted and the thicker part of the spindle is seized by the rubber ring h. Retraction of the striker a permits a detonator carrier f to swing under the action of a spring g to align the detonator with the striker. On impact, the plate e<4> is broken and the spring e<2> effects rotation of the sleeve e to release the balls d. The spring i then projects the striker on to the detonator. If the spring e<2> fails to function, the striker and spindle c remain coupled together by the balls, and the spring i operates to creep the spindle gradually downwards against the friction-grip of the rubber ring h until the portion c' is reached. The spring then impels the striker and spindle on to the detonator to effect destruction of the bomb. An electric delayaction bomb fuze is shown in Fig. 2. A contact-making plunger p has a conical end engaged in a rubber ring r. The plunger is locked by a ball o held in position by a momentum member m, motion of which is prevented until a screwed arming spindle l is retracted by a wind-vane k. On impact, the member m is thrown forwards and frees the ball o. This releases the contact-plunger p, which is slowly forced by its spring q through the ring r until contact is made. The fuze embodies an electric igniter s in series with a dry cell and a mercury switch.

Abstract: A process for the manufacture of compounds of the general formula <FORM:0688760/IV (b)/1> wherein Y is a mono-alkylamino, di-alkylamino, or mono-cycloalkylamino, and X may be alkyloxy or one of the radicals represented by Y, the alkyl groups in each case containing not more than eight carbon atoms, comprises reacting together in solution in an organic solvent a compound of the general formula <FORM:0688760/IV (b)/2> with a hydrofluoride of a tertiary amine having a base strength at least as great as that of pyridine. When X and Y are each dialkylamino radicals, a dialkylamine may be reacted with phosphorus oxychloride in the presence of the tertiary amine to form a mixture of the bisdialkylamino-chloro-phosphine oxide and the hydrochloride of the tertiary base.  Ammonium or potassium fluoride in strong aqueous solution is added, which reacts with the amine hydrochloride to form the amine hydrofluoride which with the bis-dialkylamino chloro-phosphine oxide reacts to give the bis-dialkylamino fluoro-phosphine oxide.  Alternatively, the tertiary amine hydrofluoride may be prepared separately by the process of Specification 692,774, followed by the addition of the bisdialkylamino-chloro-phosphine oxide.  As a further alternative, a solution in an organic solvent of a hydrochloride of the tertiary base, and the compound <FORM:0688760/IV (b)/3> are reacted with a strong aqueous solution of potassium or ammonium fluoride.  The "strong aqueous solutions" of the fluorides contain at least 15 g. of anhydrous potassium fluoride or 10 g. of anhydrous ammonium fluoride per 100 g. of solution. Chloroform is a suitable solvent, and methyldibutylamine and diethylcyclohexylamine are suitable tertiary amines.

Abstract: 285,692. Hancock, J. S., and Macmenigall, W. H. May 4, 1927. Moulding pulp. - In a machine for moulding pipes from a mixture of fibre and oementitious material, the pipes are formed on mandrels 11 carried between discs 2 on a shaft 1 supported by a verticallymovable frame D. The lowest mandrel takes up material from the felt 16 of a sheet-forming machine driven by a roller 17, pressure being applied to the shaft 1 by a weight P through linkage, and being reduced by means of a sliding roller Q as the shaft 1 rises during the formation of the pipe. The discs 2 are locked in position by keys 9 which engage in holes 3<a> and are attached to collars 6 on the shaft 1, so that they are removed when a predetermined thickness of material has been applied. The discs then rotate due to the initial impetus given by the roller 17, the mandrel with the finished pipe drops out since the retaining keeper 3b is removed in the lowest position, and the discs are stopped with the next mandrel in the lowest position by the engagement of the keys 9 with the next pair of holes 3<a>.
